NASA Kennedy Space Center Propellants and Life Support Branch banner

The NASA Kennedy Space Center Propellants and Life Support (PLS) Branch offers one-stop access to over 30 liquid propellants, pressurants, chemicals, and special fluids. PLS schedules, coordinates, and implements delivery, storage, chemical analysis, and distribution of more then $40,000,000 of propellants each year to support the Space Shuttle, Atlas, and Delta launch vehicles, the International Space Station and the payloads which fly aboard them.


WELCOME TO THE PROPELLANTS AND LIFE SUPPPORT BRANCH

Our office is the Responsible Center For NASA-Wide Aerospace Fluids Acquisition and Management.  We provide NASA the most cost effective and reliable sources of liquid propellants, gases, and special aerospace fluids.  Specific expertises are:
  • Leadership in acquisition of aerospace fluids under the Consolidated Contracting Initiative, and execution of technical and administrative contract support
  • Core technical expertise in cryogens, gases, hypergols, hydrocarbons, and special aerospace fluids
  • Knowledge of market conditions affecting availability and costs of required fluids
  • Monitor new program fluid requirements, assess the impacts to current supply sources,  and develop strategies for support
  • Monitor consumption and costs of major fluids used Agency-wide, and develop strategies for improved fluids logistics
  • Represent the Agency on professional, technical, and legislative issues related to fluids logistics

Locally at KSC, PLS duties include:

  • Responsible for propellant and life support services and equipment provided under KSC base operations contract to operate and maintain the Government’s largest and most diverse inventory of propellants and life support equipment
  • Responsible for the storage and distribution of 28 different fluids at KSC, Cape Canaveral Air Force Station, and to other local customers
  • Provide technical expertise to the design and operation of propellant systems to support space flight hardware processing
  • Direct servicing of Shuttle flight hardware (fuel cell oxygen and hydrogen, portable water deionization units, helium and nitrogen pipelines)
  • Unique fluid storage and supply (Refrigerant 21, Halon 1301, high purity anhydrous ammonia, and high purity liquid oxygen)
  • Oversee design, manufacture and then operate unique support equipment such as: hypergol containers, spacecraft fueling GSE, liquid helium conversion system, liquid oxygen tankers, SCAPE, liquid air packs, and N2O4 Molecular Sieve
  • Liquid Air Manufacture and use
  • Provide operation and fluids engineering support to Shuttle, Constellation (Ares/Orion), Atlas V, Delta II and IV, Pegasus space launch systems, the International Space Station, and all KSC/CCAFS spacecraft missions.
